Let me look for some blog material… (\uff1b\u2200\uff1b)<\/h2>\n\n\n\n

While I was thinking that and patrolling Amazon… \u266c<\/p>\n\n\n\n

Waitley Makita compatible battery 18V BL1890 9.0Ah Makita<\/a><\/strong><\/p>\n\n\n\n

I see a pretty huge battery here… what is this?
Looking closer…Wait? It says “9.0AH-18V”<\/strong>? That’s written on it…<\/p>\n\n\n\n

This is just crazy… (\u00b4\u2200\uff40*)\uff73\uff8c\uff8c
Anything goes. There’s a world here where things are made possible under the guise of “compatible.”<\/p>\n\n\n\n\n\n\n\n

\"\"<\/figure>\n\n\n\n

It’s just really tall.<\/p>\n\n\n\n

It’s almost square at this point.
It weighs about 0.87 kg, so holding it in your hand feels quite solid and hefty, doesn’t it?<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

It claims to have obtained various certifications… but I wonder what the reality is…
You don’t really feel like investigating, do you?<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

From what I can see here,it gives the impression that<\/strong>“it functions as a battery.”

You can’t tell if a battery is good or bad from the outside, after all.
“Lithium batteries are super scary,”<\/strong>so I only use ones I can absolutely trust.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Product features?<\/p>\n\n\n\n

Model: WTL1890 18V compatible battery 9.0Ah battery type: lithium-ion battery (Li-ion).Continuous usage time is 3 times longer than the conventional BL1830<\/strong>
\u2191Well, that makes sense…<\/p>\n\n\n\n

\u2605High performance: an inexpensive yet high-quality 18V battery!<\/strong>Full-speed charging technology: fast charging is possible.<\/strong>Remaining capacity display + self-diagnosis: the battery status is displayed on the lamp! BL1860B BL1815 BL1830 BL1840 BL1850 BL1860Also compatible with rapid chargers like the DC18RC.<\/strong>A replacement battery with lifespan characteristics, charging time, and continuous usage time at the same level as genuine products\u2014an 18V compatible battery.<\/strong>
\u2191I’m a bit worried whether it can really handle rapid charging… I wonder how it actually performs.<\/p>\n\n\n\n

\u2605Forced cooling:Since self-discharge is minimal, you can work at near full charge even after long storage.<\/strong>The control board is equipped with a protective circuit that controls charging! High-quality model with cells that have a reputation for stability. Much more economical and stress-free than replacing the battery every year\u2014a high-performance 18V battery that delivers.<\/p>\n\n\n\n

The issue is“durability and rapid charging,”<\/strong>right?
It depends on how many units you use and how often…
but in any case,“genuine batteries”<\/strong>are the safest bet.<\/p>\n\n\n\n

<\/p>\n\n\n\n

If you use it very infrequently, it might be okay, but for work-based use, problems are more of a hassle.
Even if returns and exchanges are possible, it’s“better if it doesn’t happen”<\/strong>in the first place\u2014that saves time.
A one-year warranty, and if it breaks after a year, it just doesn’t sit right. That’s how it is.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


The compatible battery side claims compatibility, but it’s unclear.
“Can charge”<\/strong>\u2260“Makita charger compatible.”<\/strong>I don’t think so.

Considering the worst case,“it feels like it goes beyond the realm of ‘at your own risk.'”<\/strong><\/p>\n\n\n\n

<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

Among all this,“positive reviews”<\/strong>also
appear. Well, if you can buy it at this price and nothing goes wrong, you’d definitely be happy, right? \u266a<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

Like this,“opinions as expected”<\/strong>also appear.
It’s a common pattern with cheap batteries\u2014“breaks easily”<\/strong>

“returns and exchanges are fine, right?”<\/strong>I sometimes feel like they’re selling with that attitude.
Honestly, Amazon has“products that are good and bad in that way,”<\/strong>right?

Some are acceptable, but others are problematic.
This time’s“compatible lithium battery”<\/strong>is something you really need to be careful about.


First of all,“buying is easy,”<\/strong>but“you need to think about disposal beforehand.”<\/strong>
You can’t throw it out as “non-combustible trash,”<\/strong>and disposal requires“research.”<\/strong>
<\/p>\n\n\n\n

In the end,“the batteries you need”<\/strong>should be“genuine batteries,”<\/strong>I think.
For cameras, GoPro, and Makita,<\/strong>I only use genuine batteries.
This is because I once“used a compatible battery”<\/strong>and had a bad experience.

“Battery-powered”<\/strong>devices are“all about the battery,”<\/strong>so“reliable genuine batteries”<\/strong>are the way to go.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Going even further… there’s also a 9.5Ah-18V…<\/a><\/h2>\n\n\n\n

Really?<\/p>\n\n\n\n

<\/p>\n\n\n\n
